LocalHero1953 Posted October 11 Share #161 Posted October 11 (edited) Advertisement (gone after registration) My Summaron LTM, bought from Scrapbook on this forum a while ago, (plus a SBLOO, a gift from Pyrogallol!). Although the s/n indicates it should be a 1960 M version according to the wiki, it has a minimum focus mark of 1m/3'4", so I assume it's an original screwmount. Marked German-made. It feels right at home on my Barnacks, though I occasionally switch to a W-Nikkor 3.5cm f/2.5 and, to be really minimalist on a Leica Standard (avoiding the external VF), a Summitar 5cm.

wlaidlaw Posted October 11 Share #162 Posted October 11 My 1M/LTM 35/2.8 Summaron is serial number 1904816. I think that dates it to 1959. Wilson Link to post Share on other sites More sharing options...

UliWer Posted October 11 Share #164 Posted October 11 46 minutes ago, LocalHero1953 said: - if that is correct. None of these lists are really correct. Thiele gives 1960 for the batch with 1783xxx. And you never can be sure whether it is an original LTM or M version by the serial number. The minimal focal distance is much more indicative. People in the German forum have tested whether an M-version with the original adapter screwed off will focus correctly: it doesn't as the adapter fitted at the factory is different from the usual LTM-to-M-adapter. 1 Link to post Share on other sites More sharing options...

I was getting confused with my LTM 50/1.5 Summarit, which is 1959 or just pre-Summilux. Wilson 1 Link to post Share on other sites More sharing options...

With all respect to the people who did the test, I do not believe the result. If you look side by side at an original LTM and a M summaron 35mm f2.8 with its adapter removed you will see their barrel is identical to the point that the LTM version base is (uselessly if used on a LTM body) machined as to fit in the adapter of the M version. edit: Maybe they tried with the M3 version, then the failure was expected.

That is what I feel they meant, that you cannot unscrew the spectacles, leaving an M39 mm thread, which will mount on an LTM but cannot focus correctly, as the rangefinder expects to operate through correction lenses.
